Estimated Delivery Timeline

Built from lightweight yet durable aluminum alloy, the frame features internal cable routing for a clean look and improved cable protection. Front and rear thru-axles increase wheel stiffness, delivering more precise handling, improved power transfer, and greater stability when riding at speed or tackling technical trails.
The responsive single-air-chamber suspension fork provides 140mm of travel to absorb impacts and smooth out rough terrain. An integrated lockout system allows you to switch between efficient climbing performance and active suspension, making transitions between trails and smoother surfaces effortless.
The SHIMANO DEORE M6100 1×12-speed drivetrain delivers precise, reliable shifting across a wide gear range. The simplified single-chainring design reduces maintenance while providing the gearing needed for steep climbs, fast descents, and demanding trail conditions.
Large 29-inch puncture-resistant tires provide excellent traction, rollover capability, and confidence on loose dirt, gravel, and uneven terrain. Paired with SHIMANO MT200 hydraulic disc brakes, the bike offers powerful and consistent stopping performance in both dry and wet conditions.
Available in three frame sizes to accommodate a wide range of riders:
S (16"): 160–175 cm (5'3"–5'9")
M (18"): 170–185 cm (5'7"–6'1")
L (21"): 175–198 cm (5'9"–6'6")
The optimized frame geometry promotes a comfortable, balanced riding position, helping riders of different heights enjoy better control, efficiency, and comfort on every ride.
